Pluperfect (Past Perfect) Subjunctive The past perfect subjunctive is the past (imperfect) subjunctive of “haber” + the past participle. Remember that the way you get the past (imperfect) subjunctive root is to go to the third person plural of the preterit. The preterit of “haber” is “hubieron.” hubiera hablado hubiéramos hablado hubieras hablado hubierais hablado hubiera hablado hubieran hablado
